We found a recording issue on the headset-mic recently, sometimes users plug a headset and select headset-mic from UI, but can't record any sound from headset-mic. The root cause is the determine_headset_type() returns a wrong type, e.g. users plug a ctia type headset, but that function returns omtp type.
In the past, determine_headset_type() worked well because the internal mic is connected to the codec, so the "Input Source" or "Capture Source" is internal mic by default when users plug a headset, the determine_headset_type() will not be called unless users select headset-mic from UI, when users select headset-mic, the plugging action already finished and the headset is completely plugged into the jack, so determine_headset_type() could return a correct type.
But more and more machines connect the internal mic to the PCH now, and the "Input Source" is headset mic by default, when users plug a headset, the determine_headset_type() will be called immediately, if the headset is not completely plugged in, it will return a wrong type.
Here add 2s delay before calling determine_headset_type(), and since there is a pop-up dialogue when users do plugging action, to avoid freezing the UI, use the deleyed_work to call that function.
